MEANS TO PRODUCE 0'! HOT GLASS.

Original application filed .Tune 1, 1920, Serial Nb. 385,590, new Patent No. 1,458,290, dated May 1, 1923. Divided and this application filed December 18, 1922. Serial No. 607,480.

To all whom it may concern:

Be it known that I, LEONARD D. Sonnlnn, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Implrovements in Means to Produce Charges of ot Glass, of which the following is a specification. My invention relates to means for feeding molten glass from a container and forming it into gobs-or mold charges of suitable size, shape and condition for entering the molds of a glass forming machine; It is at present customary to cause glassio flow or issue from an outlet opening in a container and periodically sever the lass to form individual masses or gobs w ich are introduced into the molds.

An object of my invention is to provide suitable means acting on the descending column or stream of glass to shape and sever it into individual gobs or mold charges of suitable conformation, at the same time subjecting the surface of the charges to a heat treatment by which any shear'marks, chilling effects of the cutters, or other undesirable chilling of the glass is prevented. These shaping, severing and heating operations take place without interrupting the continuous and substantially uniform flow of glass? Other features and advantages of the invention will appear hereinafter.

The present applicationis a division of my copending application Serial Number 385,590, method of and means for feeding molten glass, filed June 1, 1920, now Pat-ent" No. 1,453,290, issued May 1, 1923.

In the accompanying drawings:

Figure 1 is a part sectional elevation of mechanism embodying the principles of my invention. 4

Figure 2 is a longitudinal sectional elevation through one-of therolls and its supportin member.

igure'3 is a section at the line 1II III on Figure 2.

Figure 4a is "a plan view of the forming rolls shown in Figure 1, and also shows the glass in section.

The molten glass 10 issues from an outlet opening 11 in the'.bottom of a container 12 and flows downwardly through a passageway provided by a pair of shaping rolls 13. The rolls are mounted for continuous rotation on a pair of non-rotating cylindrical carriers or drums 14. These drums are provided with arms 15 pivotally supported on a stationary pivot rod, 16. The rolls 13 are rotated by means of gears 17 fixed to the rolls and running in mesh with gears 18 carried on drive shafts 19. The peripheries of the rolls 13 ar held together under a yielding pressure applied by means of springs 20 operating through rolls 22 mounted on the shafts 19 and having their peripheries in rolling contact with the rolls 13.

Theperipheries of the rolls 13 are formed with recesses 23, herein shown as semi-circular, so that there is provided between the contacting surfaces of the rolls a. circular passageway 24: through which the glam descends. Cutter blades 25 are mounted in the rolls 13 preferably at diametric opposite positions and are secured by screws 26. These blades extend across the receses 23 and are so arranged that as the rolls rotate, the cutting edges are brought together and sever the glass, as indicated in Figure .1. The

severed gob 27 dro s into a mold 28.

Each of the "ro l-supporting drums 14: is mounted on a stem 29 havinga passageway 30 extending longitudinally therein and terminating at its outer end in a radial passageway 31 extending through the side wall of the stem. The rolls 13 are provided with a multiplicity of radial passageways or openings 32 which extend from the central opening of the roll to the surfaces of the gob forming cavities 23. Each roll 13 fits closely on its stem'29 and as the roll rotates, the openings 32 are succe$ively brought into register with the passageway 31. A combustible gas supplied. through a pipe 33, flows through the passageway 30, 31, and openings 32. Thisv gas as it emerges from said openings is burned, thereby en any shear mark or chilling effect of the cutter, and prevent undue cooling of the glass, or where desired, to raise the temperature of the glass and leave it in suitable condition to readily conform to-the shape of the molds. I

. Means for" circulating a cooling liquid comprises an intake pipe opening into the bottom of the drlnn 14. The stem. 29

is formed with longitudinal flanges 36 by which the hollow space within the drum is separated into.lower and upper compartments. The water or other cooling 'fluid' flows forward through thelower' compartment and after passing beyond the flanges or partition walls 36, moves upward and is returned through the upper compartment to the outlet pipe 37. 1

- running with their peripheries in contact and having gob forming cavities in their peripheries, and means to. supply burning gas to said cavities.

c 3. The combination of a roll, a stationary hollow stem on which the roll is mounted for rotatiom a multiplicity of radial open ings or passageways extending through the roll from said stemto the periphery of the roll, and means for supplying a combustible gas through the stem to said perforations.

4. The combination of a roll, a stationary hollow stem on which the rollois mounted for rotation, a multiplicity of radial openings or passageways extending through the roll from said stem to the periphery of the roll, and means for supplying a combustible gas through the stem, the latter having a lateral passageway from its center to its periphery, whereby during the rotation of the roll said perforations are brought successively into communication with said lateral opening.

means to provide burning gases to envelop the glass in its passage throughsa'id channel, and means to cause the Walls of the channel to move downward with the de-- scending glass.

7. The-combination of means for flowing a stream of molten glass, forming means to surround the stream and moving downward withthe glass, and means to supply a guiding pressure between said forming means and the glass. e 1

8. The combination with means to flow a stream or column of molten glass, of a pair of forming rolls provided with'recesses in their peripheries arranged to embrace the flowing glass, and means to supply burnin gas to envelop the glass .as it passes etween the rolls.
